There are two ways of reporting creatinine.
One is the amount that appears in the urine (called the
clearance).
This is done to see extent of filtering capability of the kidneys. A low figure here is bad, meaning the kidneys are not working right.
The other test is on the blood serum... it is called just creatinine.
It is taken and shows how much creatinine is in the blood needing to be removed. A low figure here means your kidneys are functioning well.
When you read about creatinine CLEARANCE this involves the filtering capability of the kidneys. It is often referred to in article about drugs, because drugs are removed from the body thru the kidneys. Poor clearance means the drugs build up in the body. Then their doses must be adjusted to account for this or that drug not used at all...a doctor's decision.
